a 75w TC mod will run almost anything you can throw at it. . The only time one TRULY needs more then 75w is with monstrous handmade coils. Or some of the crazy prebuilt coils you can get with the Smok TFV4 and TFV8 tanks and Im sure theres a couple other prebuilt coils that can handle or demand more then 75w. But I run SS fused claptons in dual coil at about 50-60w all day and the flavor is perfect for me. The main reason you see all these 100,150,200,213 watt mods is 2 fold
These 100+ mods are all 2 or 3 cell batteries which means you have to switch your batterie sout a lot less then a single battery mod which all max out due to power available at 80ish watts
so if you are going to make a mod that holds 2 or 3 batteries its going to be able to supple 150-200+ watts. SO why not just make them so they can do that. DO many people even really use their devices at 200w. Im sure some have for shits and giggles, but I doubt many if any people run at 200 w all day long.
So a 75w mod is actually a great mod. I have 1 in my rotation. Its the IPV d2 it only does 75w and can do anything i need it to do. AN dit gets used EVERY DAY
The other reason you see so many of them is its just marketing. "Our mod does 150w" "yeah well ours does 151w" "So our mod does 175w" etc etc
SO if your happy with your picio...put your money into a tank The tank and coils are what make flavor oh and good juice
The crown has been the default best all around tank with prebuilt coils. Some like this one better, or that one better. But I feel you cant go wrong with a crown.
ecig.com usually has great prices on the coils. Usually $8 or less for a 4 pack
